 broader than the prothorax, but the margin not raised, sides 

 slightly roiuided, broadest about middle ; uj^per surface convex, 

 gradually declivous behind, with regular and distinctly punctured 

 strife ; the intervals slightly convex, smooth, finely aciculate and 

 with regular rows of short depressed white setae ; colour black, 

 with dense even scaling, which is either pale grey mottled with 

 pinkish brown, or greenish grey above turning to pink laterally.

Very similar in general facies to the preceding species, but 

 diSering in important details, such as, the absence of the long- 

 erect setse, the presence of the curved sulci on the rostrum, the 

 non-plicate forehead, and the less deeply punctured and non- 

 marginate elj^tra. P. palliatus Fahr. is a more slender insect, 

 with the anterior legs, and especially the tarsi, much longer ; the 

 elytra are truncate at the base and the rostrum has a short 

 carina on each side of the central furrow. 



Piazomias pratensis, sp. nov. 



Long. ^-^, lat. 11-lf mm. 



Head broad, convex, coriaceous, and with a fine central stria, 

 with dense scaling, which is dark brown above scattered with pale 

 squamiform setse, and grey beneath and round the eyes. Rostrum 

 as long as head and gradually narrowed from base to apex ; upper 

 surface with a central depression containing a distinct fovea 

 which is usually connected with the cephalic stria ; scaling as 

 on head. Antennce piceous, similar to those of P. varicolor. 

 Prothorax as long as broad, base truncate, apex scarcely narrower 

 and slightly lobate, sides rounded, broadest at middle ; upper 

 surface convex, with a distinct transverse impressed line just 

 behind apex and a very fine central stria, which is often absent ; 

 colour black, with dense dark brown scaling and a sub-lateral and 

 infra-lateral paler stripe on each side, also some scattered pale 

 squamiform setse. Elytra subovate, the basal margin scarcely 

 broader than the prothorax, truncate and not elevated, sides 

 moderately rounded, broadest rather behind middle ; upper 

 surface convex, steeply declivous behind, with distinctly punc- 

 tured stride, the intervals slightly convex, sraooth, aciculate, and 

 with rows of very short suberect pale setaa ; colour black, with 

 dense dark brown scaling which is somewhat paler laterally. 

 Legs with dense scaling and pale setse ; tibise crenulate internally, 

 except the posterior pair.
